Mindfulness is a modern movement, appropriated from ancient Buddhist roots, and clinically innovated by Jon Kabat-Zinn. The practice of mindfulness involves being aware moment-to-moment, of one’s subjective conscious experience from a first-person perspective. When practising mindfulness, one becomes aware of one’s "stream of consciousness". The skill of mindfulness can be gradually developed using meditational practices that are described in detail in the Buddhist tradition. The Five-Aggregate Model, an ancient link between mind and body, is a helpful theoretical resource that could guide mindfulness interventions. The term "mindfulness" is derived from the Pali-term sati which is an essential element of Buddhist practice, including vipassana, satipaṭṭhāna and anapanasati. It has been popularized in the West by Jon Kabat-Zinn with his mindfulness-based stress reduction (MBSR) program.
